The track on a railway (non-US) or railroad (US), also known as the permanent way, is the structure consisting of the rails, fasteners, sleepers and ballast (or slab track), plus the underlying subgrade. For clarity it is often referred to as railway track (British English and UIC terminology) or railroad track (predominantly in North America).
The term permanent way also refers to the track in addition to lineside structures such as fences etc.
